Read My Comment on the Write Higher Order Arrow Functions challenge

Tell us what’s happening:

If I may suggest you to first explain how map() filter() and reduce() work before challenging it. Otherwise is awsome!

Your code so far

const realNumberArray = [4, 5.6, -9.8, 3.14, 42, 6, 8.34, -2];
const squareList = (arr) => {
  "use strict";
  // change code below this line
  const squaredIntegers = arr.fiter((post) => ;
  // change code above this line
  return squaredIntegers;
// test your code
const squaredIntegers = squareList(realNumberArray);

you are right that it may needs explanation before… there is a new version of the challenge in the beta version of FCC, which will be eventually deployed

why don’t you take it as a chance to find how to search the documentation? try to find on your own how these work! it is good practice!
